Twelve researchers from 11 countries used autoethnographic techniques, keeping diaries over 10 weeks of the COVID-19 crisis, to observe and reflect on changes in the role and cultural authority of science during important stages of viral activity and government action in their respective countries. We followed arguments, discussions and ideas generated by mass and social media about science and scientific expertise, observed patterns and shifts in narratives, and made international comparisons. During regular meetings via video conference, the participating researchers discussed theoretical approaches and our joint methodology for reflecting on our observations. This project is informed by social representations theory, agenda-setting, and frames of meaning associated with the rise and fall of expertise and trust. This paper presents our observations and reflections on the role and authority of science in our countries from March 10 to May 31, 2020. This is the first stage of a longer-term project that aims to identify, analyse and compare changes in science-society relationships over the course of the ongoing COVID-19 pandemic.

Activists, social organizations and members of citizen collectives in Mexico and Latin America have assumed not only the fight for water and territory, but also the difficult task of interacting with experts in different scientific fields, and the challenge of placing their causes in the public space. They take the role of cultural mediators between affected people, scientists and politicians within hybrid transdisciplinary working groups. Within the framework of these groups' actions, a new current of communication of science has emerged, one that shifts its interest from encouraging involvement with scientific knowledge for its own sake, to untangling, understanding and communicating socio-environmental issues for the explicit purpose of contributing to social transformation.

World’s Fairs and scientific-technological theme parks have been
propitious places for the communication of science and technology through
modernity. This work addresses the issue of the construction of public
discourse about the future within these sites, as well as the changing role
attributed to science and technology as mediators in the relationships
between nature and society. In both fairs and parks, science and
technology play a leading role in the construction of the discourse about
the desirable and achievable future. The practices of science
communication and technology have specific forms, strategies and
objectives, depending on the purposes of the discourse enunciators at
different historical moments. This is exemplified through two cases: the
1939 New York World’s Fair and the EPCOT center in the U.S.
